Virtual physics is the collection of programs simulating physical phenomena. They can be used as demonstration tools at school or for individual studies and experiments at home. See what you can never see in nature! The most exiting feature of Virtual Physics is that you can perform and observe many experiments you can never see either in nature or in the school laboratory, eg. stars moving on their orbits or the motion of the molecules of gas. The program consists of 13 modules covering: Diffraction, Dynamics, Electrostatics, Gravity, Kepler Laws, Kinematics, Kirchhoff Laws, Optics, Oscillations, Projectiles, Thermodynamics, Vectors and Waves.
With the Diffraction module you can observe diffraction. It occurs when light bends around an obstacle or, as in our experiment, passes through a slit. If the slit is comparable or narrower than the length of the light wave, the light bends. In fact the slit acts then as a separate wave source.
With the Dynamics module you can investigate the motion of a block sliding down an inclined plane as a result of Earth's gravity force. You will be able to see vectors of the forces exerted on the block.
In the Electrostatics module you can see how the electric field, generated by a set of static charges, looks like. Both the strength and the potential of the field can be represented by color intensities in the simulation window.
With the Gravity module you can investigate gravitational interactions of celestial bodies. You can define two, three or more objects like stars, planets, comets, spacecrafts etc. The simulation window can be enlarged to full screen mode.
Kepler module lets you investigate motions of planets and other celestial bodies in our Solar System. While this is a relatively simple, two-dimensional model, it is very helpful in understanding Kepler's laws.
With the Kinematics module you will see how the same motion can be described in a number of equivalent ways, using various terms. This module shows also how
